Limestone was converted to high surface area CaO/MgO catalysts via calcination-hydration-dehydration (CHD) method for transesterification of coconut oil to biodiesel. Thermal decomposition at 900°C transformed dolomite CaMg(CO3)2 to large crystallite and low surface area CaO/MgO. CHD treatment elimi...
